UNDERSTANDING PCOS
What is Polycystic Ovarian Syndrome?
Polycystic ovary syndrome (PCOS) is one of the most common hormonal conditions in Australia, affecting approximately 1 in 10 women of reproductive age. It is characterised by elevated androgens (male hormones), irregular or absent ovulation, and — in many cases — insulin resistance.
Despite the name, you do not need to have polycystic ovaries to be diagnosed with PCOS. The condition presents differently in every person, and symptoms can range from mild to significantly life-altering. Because insulin resistance underpins the majority of PCOS cases, diet is one of the most powerful levers for managing the condition.
Research consistently shows that targeted dietary changes — particularly a low-GI, anti-inflammatory approach to PCOS — can improve insulin sensitivity, regulate periods, support healthy weight, and reduce androgen-driven symptoms. Our Perth PCOS dietitians are here to help you navigate that process.

PCOS is not a one-size-fits-all condition. Understanding which type or combination of types you have helps your dietitian build a more targeted, effective nutrition plan.
The 4 Types of PCOS
RECOGNISING THE SIGNS
Common Symptoms of PCOS
PCOS can affect many systems in the body. If you recognise several of the following symptoms — particularly alongside irregular periods — it's worth speaking to your GP and a specialist PCOS dietitian in Perth.
01.
Irregular Periods
Infrequent, absent, or unpredictable menstrual cycles (oligomenorrhoea or amenorrhoea) — one of the hallmark signs of PCOS.
03.
Acne
Persistent acne on the face, back, or chest linked to elevated androgens like testosterone — often unresponsive to standard treatments.
05.
Blood sugar issues
Cravings for sugar or carbohydrates, energy crashes after meals, and increased risk of type 2 diabetes are all linked to insulin resistance in PCOS.
02.
Weight Gain
Difficulty losing weight or unexplained weight gain, particularly around the abdomen — often driven by insulin resistance.
04.
Fatigue
Persistent tiredness and low energy, often worsened by blood sugar instability, poor sleep, and underlying inflammation.
06.
Fertility Issues
Irregular or absent ovulation is a key driver of fertility challenges in PCOS, which accounts for the several anovulatory infertility cases.
PCOS NUTRITION STRATEGIES
5 Evidence-Based Dietary Strategies for PCOS

There is no single PCOS diet, but robust research consistently points to a low-GI, anti-inflammatory approach as the most effective nutritional framework. Here are the key strategies our Perth PCOS dietitians recommend:
1. Follow a Low-GI Eating Pattern
Choosing low glycaemic index carbohydrates — oats, legumes, sweet potato, whole grains — reduces blood glucose spikes and lowers insulin levels, directly targeting the root driver of most PCOS cases.
2. Prioritise Protein at Every Meal
Adequate protein (eggs, legumes, fish, chicken, tofu) slows glucose absorption, supports satiety, and helps stabilise blood sugar — making it one of the most practical tools for managing PCOS hunger and cravings.
3. Increase Anti-Inflammatory Foods
Oily fish, extra-virgin olive oil, berries, leafy greens, nuts, and seeds help reduce the chronic low-grade inflammation that worsens PCOS symptoms and drives androgen production.
4. Support Key Micronutrients
Many people with PCOS are deficient in vitamin D, magnesium, zinc, and inositol — all of which play roles in insulin signalling and hormone regulation. A dietitian can assess your individual nutrient status and advise on food-first strategies.
5. Support Your Gut Health
Emerging research links gut microbiome diversity to PCOS severity. A diet rich in prebiotic fibre (garlic, onion, leeks, oats, legumes) and fermented foods supports a healthy gut microbiome and may improve androgen levels and metabolic health.
